Flow

Including the rainfall intensities in the Link Hydrograph Output Table, will enable the the rainfall profile to be superimposed onto the Level/Depth profiles.

The rainfall contained in the Design Report just indicates Peak and Average Intensities. The total rainfall for the storm event should also be documented, particularly as the first 5mm of rainfall now requires interception. There will be some even...

The text contained within the Results page is quire small and not easy to read. It would also reduce the prospect of miss reading a line of data.

Add a column called ‘Infiltration Volume’ to the simulation results table which indicates the total volume of water infiltrating into the ground at the upstream manhole during the selected storm.

This is especially applicable now given some areas may have 100% impermeable while other will have greenfield with a possible option to turn to impermeable. Users can also adjust Cv value locally. The design report should contain the new additions.

We have recently been challenged by Wiltshire LLFA regarding half drain times. As I understand it, Flow calculates the half drain time to CIRIA 156 which gives a significantly longer half drain time than the BRE365 method that Micro Drainage uses....

Always having mass balance issues when utilising flow through structure. It could be something from adding orifice to inlets same size as pipe, lifting/dropping structure slightly increasing/decreasing length of structure, that sorts the issue. Th...

Add a column for manhole cover loading classification on manhole schedule. Required for S104 and construction plans

The cumulative area calculation discounts everything before a flow through structure and the nodes attached to the structure. LLFA's are now requesting calc files due to the print out also reading your incorrect pathing of calculations. Theirs no ...
